Table 1. 12 V DC Power Input Terminal Block Connections
Accepts 12 volts dc nominal from an AC/DC converter or
other 12 volts dc supply.
Analog Input used to monitor an external charging source.
Supplies reverse polarity protected source voltage to external
devices.
Supplies switched power for external devices.
Table 2. 24 V DC Power Input Terminal Block Connections
Accepts 24 volts dc nominal from an AC/DC converter or
other 24 volts dc supply.
Supplies reverse polarity protected source voltage to external
devices.
Note: This is preferred wiring method, since it ensures
that removing power from the ROC800 CPU also
removes power from the FFI.
